`PICKER l'SPNDLE FOR LOOMS Filed Feb. ll, 1932 l. OO

Patented Feb. 5, 1935 L, assigner todi .om .WorksWorcesten l Mass., a" eo171:@rationV of'Massachusetts 7 Animaties February 11,119.32, serial Naseem@ This invention relates-to picker spindles and it is the general object of the inventionto yprovide arspindl which is self-lubricated sor` as torender unnecessary the application of oil directly tothe spindle. v 1 l rBox looms 1and the'plain end of `certain weft replenishing looms are provided with picker spindles along which the shuttlepropelling lpicker moves. yThese spindles .become 'heated 'unless properly lubricated, but because of-th'e'danger` of spattering oil on the yarn and fabric, the spindle is oiled very sparingly. As a consequence, suillcient heat sometimes develops' toy bend the picker 'spindle in its mounting the result .of .which is to 'the effect of which is to lhold the absorbent'material firmly in position. The",out er end ofthe chamber may be closedby any suitable valve, such as that found on various lubricating systems, and the hole connecting the groove with the chamber suii'iciently` large to permit a sumcient feeding of oil to keep the spindle properly lubricated.

It is a further object of my invention to provide the spindle with an internal reservoir of oil,

which communicates with a longitudinal groove on the periphery of the spindle at a point along the spindle which is between the endsof the picker when the latter is in normal non-picking position. In this way assurance is given that as soon as the oil arrives in the groove it will be in position to lubricate the picker bore. The picker Will ordinarily move along the spindle in the direction away from the point of communication between the groove and reservoir. By this arrangement the interior of the picker bore is in most favorable position to be lubricated during periods of inaction on the part of the loom. In assembling the various parts of the spindle I preferably insert a length of the wick into the oil chamber and pick the same so as to form an eiective anchor, after which the Wick is stretched along the groove and then clamped by means of (crise-158).

a- 'plug or the like which binds vthe metallic core y of-thewick tightly in position and serves totake -up `any slack-which might exist-in the wick. 1

With fthese and other objects in View which will i appear as'thedescription proceeds, mywinvention resides 'in the c'ombinationfand arrangementof parts'hereinafter described and setiforth'i-nthe claims. .r f i In th'efaccompanying drawing, wherein a convenient embodiment of my invention .is set forth, g

'Ihe shuttle boxes 17 are mounted for reciprocation with respect'to the lay in the usual manner so as to present one or another of a pluralityA of shuttles to active position. A picker 19 actuated by the picker stick 20 is movable along the spindle.

The matter thus far described maybe as set forth in my prior Patent No. 1,807,743. y y

My present invention relates more particularly to the spindle proper, and by referring to Figs.

3, 4 and 5 it will be seen that the shank or body e of the spindle is provided at its upper side with"v a groove 30 which extends throughout'the greater part of the length of the spindle, although it need not extend to either end, and as shown herein terminates short of the outer end of the spindle. As shown in Fig. 5 the outer end of the spindle is bored so as to aord an oil chamber 31 which may be closed by an appropriate. tting 32 having a common form of ball lockor valve 33 held in Oilretaining position by spring 34. 'I'he fitting is shown herein as screwed into position to prevent oil leakage, but it may be secured to the spindle in any other way whichwill effec- 7 tively prevent loss of oil. connecting passage 35 is provided between the chamber 31k and groove v30 and is the meansrby which oil can be transmitted from the chamber to the groove.

l VThere is located in the groove a Wick element 40 which may have a wire core formed of two or more flexible wires twisted together and gripping tufts oftextile material, such.l as felt, wool or Y cotton or any othenmaterial 'having capillary properties rendering it capable of absorbing and transmitting oil. The wick has the left hand end thereof as viewed in Fig. 2 held in positionv`v` by means of a plug 41 driven intothe spindle; j The wick lies within the groove,lvvith` the tufts thereof projecting slightly above" the cylindrical surface of the spindle to liein thep'athjofthe' picker. Y

The wick is projected through .,thecon'necting passage 35 and a sufficient amount offit is deformed as at 50 to form an anchor to prevent :loosening of the wick in the groove.. i It: is to` be understood that with fr`et1uentY reciprocating movements of the picker alongy the` spindleyit` is desirabletohold thefwicklinf position andA it is for this reason that I pack a length of :theA wick into the inner-end of-theoil chambenthe wire `core ofthe wick servingtohold the packed mass in position. n In operation, the spindle. will be appliedftov the loom so that the wick willbe facing upwardly and' by appropriatev means a quantity; of oil .will be pushed around the ball lock into the loil .charnzber. JThat part 4of the wick. Whichhas been packed into the chamber will become saturated andthe -oil will travel along-the, wick.;thro ugh' the passage 35 and along that partfof thevwick in the groove- `1As thexpicker. moves. back r-and forth it will therefore have its b ore lubricated by Y smalland unobjectionable. amounts of `oil which `perrr'iit pickingk of apart of the same into 'the end of the chamber to-form an anchor,v way Y resisting outward vmovement .of `the wick through the passage35; It willlloeY seen `by referring to Fig. 2 that the picker when in normal non-active position surrounds that part of the spindle through which the passage 35 is located, and when the oil is kfirst raised by capillary attraction through this passage it reachesV a posi-V tion where it can lubricate the pickerwhenythe latter is at rest. .This result is achieved by having .the outletwhich connects ythe oil chambery' with the groove loatedfneirt the;y outer end of the spindle and between thefends` of the" bore in the picker when the latterr is at rest. `It will "also be seen that I have vproduced an improved Iforrnjof wickhaving a metallic core which serves tokhold the wick in the groove and is not subject to stretching.` Forthls reason the wick is found "nfpractic'etolie within the groove and not be disturbed by movementsof the picker. Also, the

eyel end'of the s'pin'dle'lserves to hold the wick on the upper `sideof the spindle.
